MECHANISM FOR USE AS OB AS PART OF A IDAMPER-REGULATOB.

Specification of Letters Patent.

Application filed February 15, 1912. Serial No. 677,831.

To all whom it may concern:

Beit known that I, EnwAnoJ. Duncan, a citizen of the United States of America, residing at New York city, in the county and State of New York, have invented certain new and useful Improvements in Mechanism for Use as or as Part of a Damper-Regulator, of which the following is a specification.

My invention relates to an improved a damper regulating apparatus, and it consists. in so locating a collapsible tube containing a volatile fluid that 1t, shall receive heat from the medium to be regulated, in increasing or decreasing degree, and shall thereby so change its form and dimensions that a regulator may be operated thereby; and as a subsidiary feature, the arrangement of the parts in such form that the thermometer may be conveniently and safely carried therebv in an easily visible position.

Figure 1, 1s a side view of a device embodying my present inventlon. Fig. 2 is another view, partly in section, of such a device, in which the collapsible tube is seboilers have been. made.

tion,

cured directly to a metal base, an extension of which enters the vessel holding the heating fluid. Fig. 3 is a similar view of a device in which the collapsible tube has an independent closure, making close contact with the said metal base, but independent from it. Fig. 4 is a top plan view of the device in question. Figs. 5 and 6 are details of the so called base piece. Figs. 7, 8 and 9 represent modified devices embodying the main feature of the invention.

Various attempts at regulating steam heating and vapor heating systems and In all of the earlier ones with which I am acquainted, it has been thought necessary to have the heating medium, suchas steam or hot water, make direct cont-act'with the collaps ble tube, holding the medium whose extension was utilized to operate the damper (if an expansible tube was used). This gave rise to various difficulties in construcbut after repeated experiments, I have devised'a regulator which is'free from many of the objections of earlier devices.

In theform of device shown, there is what I term a base piece, composed of a tube like projection or extension 1, threaded on the exterior and adapted to be' or as part of,

screwed tightly into a threaded aperture a boiler, steam pipe or other vessel, the heat of the liquid within which isintended to operate the governing device. This extension 1, is provided preferably, with a longitudinal recess 2, adapted to receive and hold a thermometer 3, and to insure its proper heatlng, it is preferably of a length to extend somewhat within the inner wall of the vessel to which it is to be secured. Above the threaded portion, on one side, it extends-outwardly, preferably, at less than a right angle to its inner wall and this extenslon is carried out sufficiently to constitute, preferably, a. circular base 7, as shown in Fig. 4, sufficiently large to receive and sustain a satisfactory collapsible tube 8. On its upper face, if the tube is to be joined directly to it, I prefer to construct a circular groove 6, as shown .in Fig. 2, adapted to receive and hold such tube, and beyond the tube, a flange like extension 9, adapted to support a plate or disk 10 and its supports. The collapsible tube employed may be such as that shown in my Patent 1,010,123 of November 28, 1911. On the upper part thereof, I secure a cap 11, with a projection 12 adapted to pass through an opening in the plate 10. On'the upper face of the late 10,pillowblocks 14 are arranged to support a trip 15., through which a damper regulator may be extended. This trip 15, is provided with stops 20 and 21, one on each side of its pivot, so that on the one side its weight may not press .too hard upon the collapsible tube, and on the other side it may not turn down, so far as to permit the damper regulator lever to strike the thermometer.

The operation of the device will be manifest; Whenever there is a change in the fitemperature of the fluid within the vessel into which the base extension projects, that temperature will be communicated to the Patented Sept. 19, 1916.

base and thence to the volatile fluid 'within the collapsible tube upon that base; If it be a rislng temperature, that volatile fluid will be expanded, as will the tube 8, the pro-,

be communicated to the base piece and the volatile fluid, with results the reverse of those just noted, and tion, the thermometer would readily exhibit the damper lever accordingly,

during the entire acon its face the temperatures that were occurring.

The part 10 is usually not a box like structure, but rather a plate top with lugs or supports perforated to receive bolts 16, which pass down through them and the base, (which is provided with lugs 17), and are secured by nuts 18. These parts extend outward a little beyond the line of the thermometer and thus protect it from injury.

Instead of inclosing volatile fluid within a structure composed of the base, the collapsible tube and the cap, I sometimes employ a supplemental base 19, making close contact with the main base at 5 and 4, but not soldering, riveting or otherwise permanently securing it thereto. The heat will be communicated to the volatile fluid inclosed in this form of structure almost if not quite as readily as though there were no supplemental base 19, provided good contact between it and the main base is insured.-

I form the base piece as described in order to permit it to be screwed tightly into the wall of the containing vessel and though in some instances I might secure quite good results with a structure in which the part 4 extended out horizontally, there are other occasions when a part thus extended would prevent the forming of a satisfactorily tight joint between the base extension and the wall of the containing vessel. This struc- .ture as a whole, is exceedingly simple. It may be applied to the containing vessel readily, only necessitating a comparatively small opening for the insertion 'of the exv tension, is adapted to form a tight joint and, particularly in the form of Fig. 3, may be removed as to everything but the base piece, without opening the containing vessel, and even in the case of the form shown in Figs. 1 and 2, would not interfere with the operation of any other part of the system, in case this particular device got out of order.

As already stated, Fig. 7 represents a modified form of the device. In it, the collapsible tube is not fully shown, but is indicated at 8. The cap and the projection (not shown) are like those of the other form, but the base plate 23 instead of proje'otlng into the boiler (not shown) is located in a shunt 22 from the boiler. It is practically an enlargement of the pipe, made of a size to present sufiicient heating surface to effect the desired object. That is, the pipe 22, is so enlarged and flattened as to form a satisfactory base for supporting a tube like 8. Thedesired result might be effected by providing-acircularmetal box having a flat top like 23 and leading pipe 22, into and from it.

The novelty is in securing a suitable heat conveyer in a construction which does not permit the volatile fluid, nor its collapsible container to enter the conduit or boiler whose fluid contents are to be controlled.

pansible member of the attachment, with appropriate results. If the said base plate were itself an integral part of the wall of the fluid conduit it would not prevent the operation'of my device.

What I claim as my invention and desire to secure by Letters Patent is: a

1. In a mechanism adapted for use in a damper regulator, the combination of a base with an extension adapted to be inserted through the wall of-a vessel containing a heating medium, a second extension wholly without the line of said wall, integral with the first part, which is adapted to be inserted as set forth, said second extension being adapted toreceive and hold an expansible tube containing a volatile fluid, closed at both ends and provided with a projection adapted as described to operate a damper regulator, and a recess, located in the extension first named, and opening to the outside of the parts intended to be inserted through the wall of the vessel, but closed at the opposite end, all substantially as set forth.

2. In a mechanism adapted for use in a damper regulator, th combination of a base with an extension, closed at the end and adapted to be inserted through the wall of a vessel containing a heating medium, a second extended part wholly without the line of said wall and projecting from the extension which is adapted to be inserted as set forth, and integral therewith, and adapted to receive and hold an expansible tube containing a volatile fluid, an expansible tube closed at both ends and provided with a projection adapted as described to operate a damper regulator, the bas extension without the said vessel being arranged as described to constitute the closure of one end of the collapsible tube, all substantially as set forth.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses, this 9th day of February 1912.
